PROCESS OF MAKING- SEATS;

Application filed March 9, 1914. Serial N 0. 823,637.

To all whom it may concern Be it known that I, GUsrAVE F. DANIEL- soN, a citizen of the United States of America, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and'useful Improvements in Processes of Making Seats, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to seats for agricultural field machinery and the like, and more particularly to those formed of sheet metal or like metals, and to a method of manufacture whereby a portion ofthe seat isembossed with a design, trade name or the-like and is then molded with the rest of the sheet tothe proper conformation without distort- ,ing the design already embossed thereon. I

v The invention consists in the matter hereinafter set forthand pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of a seat blank for forming a seat that embodies features'of the invention; Fig. 2 is a cross sectional view. of dies for embossing a design or name on a seat; Fig. 3 is a plan of an embossed seat; Fig. 4-:is a cross sectional view of dies for completing the form of the seat, and Fig. 5 is a plan of a completed seat. i

It is difiicult to emboss or press up a design, figures, letters or the like on sheet metal after the latter has been bent from a plain sheet by pressure in dies, without distorting the piece and it can only be accomplished successfully by expensive compound dies. The method herein described consists first, in cutting a blank from sheet metal and stamping thereon a design, letters, figures or the like, while it is still unformed, and then in molding the blank to the desired contour without disturbing or replacing the original designj c As herein described a blank 1 is cut out from a sheet metal blank and is given the desired outline thereby. A. portion of the seat, indi- Copies of this patent may beobtained 'for appearance as an article which hasbeen first formed and then embossed as in the usual method, and may be manufactured at far less" expense and diificulty. vVhen cutting the blank 1 from sheet metal, the blank can be Specification of Letters Patent. Patented Nov, 10, 1914'. l

provided with the ordinary drain openings 8 or this punching operation can be accomplished at the same time that the dies 3 and 4 are employedfor. embossing the rim or edge of the seat.

By reference to Fig. 4, it will be observed that the die 5 is recessedto provide clearance for the characters, figures ordesign embossed uponthe rim or edge of the seat, and that the die 5 cooperates with the die ,6 in holding the rim or edge of the seat while the die 7 completes the formation of the seat, thereby preventing the rimor edge of the seat from being distorted while'the blank is being drawn to proper form.

By using a convex lower embossing die, as shown 1n Fig. 2, scales and other foreign matter are preventedifrom accumulatmgf upon the die and interfering with the preper formation of the characters or design an in consequence of this method of manufacture,

the seat'can be expeditiously and economically produced.

WVhat I claim is: p

l. A process for manufact ring seats for agricultural field machinery which consists in cutting a blank from a plain metal plate, in simultaneously bending and embossing a portion of the blankwithoutotherwise deformingv it, and in drawing the central portion of the embossed blank to form without affecting the bent and embossed. portion i I thereof. 7 a

2. A process of manufacturing seats for agricultural field machinery consisting in first cutting a blank from a plain metalplate, pressing the edges of the blank between dies toemboss and provide a convex edge for the greater part of the periphery of said blank, and holding the formed edge of the blank between dies While the remainder of the blank is drawn by a die to provide the blank with a concave portion.

In testimony whereof I affix my signature in presence of two witnesses.
